HOUSE SPRINGS, Missouri — Effective immediately, any new International Hot Rod Association (IHRA) chassis certification or renewal must be done with one of the stickers seen here. DO NOT have your car certified or re-certified with any sticker that does not resemble one of these images.

Current old-style certification stickers remain valid until their expiration date. If you’re looking to get your car’s certification up to date, email info@ihra.com and we will get you contact information for an IHRA Chassis Inspector in your area.
